Fig 2. Three-dimensional color-coded mapping of AF wave-dynamics parameters and LA geometric parameter.

Fig 2

(A) CFAE-CL, (B) DF, (C) ShEn, and (D) curvature maps. (E–G) Examples of fractionated and unfractionated EGM and their analyses. The frequency spectrum (F) and voltage histogram (G) were analyzed to compute the DF and ShEn of bipolar EGMs, respectively (recording sites are marked by black symbols). (H) An inverse relationship between mean LA wall thickness and LA volume. CFAE-CL, complex fractionated atrial electrogram-cycle length; DF, dominant frequency; ShEn, Shannon entropy; EGM, electrogram; LA, left atrium.
